GAS-BURNER TIP.

To all whom it may concern:

Be it known that I, JOHN R. LEEMING, a subject of the King of GreatBritain, residing at Somerset, in the county of Gunnison and State ofColorado, have invented new and useful Improvements in Gas-Burner Tips,of which the following is a specification.

An object of the invention is to provide a tip for attachment to a gasburning apparatus, such as miners lamps and the like, and which willprovide a clear and efficient flame. For the purpose mentioned, use ismade of 'a frusto-conically shaped body having a longitudinallyextending flue therethrough, a baffle point formed in the said bodybetween the ends thereof and a peripherally extending flange integrallyformed at the upper end of the body and having an outer octagonalsurface, the said flange being adapted to constitute a handle forremoving the tip from the lamp proper and also constituting a means forprotecting the flame produced at the upper end of the tip.

Reference is to be had to the accompanying drawings constituting a partof this specification, in which similar characters of reference denotecorresponding parts in all the views, and in which- Figure 1 is aperspective View of my gas burner tip showing the same applied. Fig. 2is a vertical section. Fig. 3 is a transverse section taken on the line3-3 in Fig. 2.

Referring more particularly to the views I provide a frusto-conicallyshaped body 10 adapted to be vertically received in the end of a gassupply pipe 11 so that no gas can escape from between the end of thesupply pipe and the body 10 at the point of connection of the supplypipe and the body. A flue 12 extends longitudinally through the body 10,that portion of the flue above the upper half of the body 10 being of asmaller diameter than the remaining portion of the flue in the lowerhalf of the body 10. At the point where the flue 12 decreases in size inthe body 10 is formed a conically shaped baffle point 13, the saidbaflie point being integrally formed in the body 10 and extend-Specification of Letters Patent.

ing downwardly in the larger part of the flue .12. Extending upwardlyfrom the upper end of the conically shaped body 10 is an integralcircular flange 14 having an outer octagonally shaped surface 15, aflame chamber 16 being formed in the body 10 by the mentioned flange 16as will be seen in Fig. 2, the upper end of the flue 12 terminating inthe chamber 16.

In the use of my device, particularly when the same is used inconnection with miners lamps, the flame at the upper end of the flue 12and in the chamber 16 will be prevented from being easily blown out orextinguished by the flange 14 which acts as a protecting wall for theflame. By providing the baffle point 13, any dust or dirt that may passthrough the gas supply pipe and enter the flue 12 will lodge in thespace formed between the end of the baffle point and the sides of theflue 12 opposite to the baffle point so that the mentioned dust or dirtwill not enter the reduced portion of the flue and tend to clog thesame, thus also tending to greatly reduce the brilliancy of the flame.

Having thus fully described the invention, what I claim as new, is

A burner tip comprising a frusto-conically shaped body having alongitudinally extending gas flue therein, the upper portion of the saidflue being of a smaller diameter than the lower portion thereof, aflange integrally formed on the upper end of the said body and extendingtherefrom to form a flame chamber in the body, the upper end of the saidflue terminating in the said chamber and a conically shaped baflieintegrally formed on the body and extending downwardly into the largerportion of the said flue, the said baffle being disposed at the pointwhere the said flue becomes smaller in diameter.

In testimony whereof I aflix my signature in presence of two witnesses.
